A nozzle plate of an ink-jet printer head is provided to solve the complexity of a conventional process for the nozzle plate by directly penetrating an ink injection hole in the nozzle plate. In a nozzle plate. a plurality of bolt engaging holes(6) are formed to be engaged with a nozzle block. A plurality of ink injection holes(5) are directly penetrated in the nozzle plate itself. A groove is formed at the periphery of the ink injection holes. A plunge is guided to the groove to accurately block the ink injection hole and thus prevent ink from being leaked. The plurality of ink injection holes may be formed in the nozzle plate in a line. The plurality of ink injection holes may be formed in zigzags.
